' SIEGMUND BACHMANN, or CHICAGO, ILLINOIS.

To all whom it may concern: Be it known that I, SIEGMUND BACHMANN a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Boxes, of which the following is a specification.

My invention relates to an improvement in the class of boxes, more'commonly'made'ofpaper board, and ada ted to be sup lied to the consumer in col apsed or knee -down condition from which they are readilyeone vertible to box-form, bya construction'in volving a hinged connection, aflorded by bending or creasing, of the walls with the base, with end-extensions of two opposite walls for folding inwardly against the inner surfaces of the walls at right-angles to said opposite walls, to reinforce the structure.

The primary object of my inventionlis to provide new and improved means for secur ing the aforesaid reinforcing medium in place, said means consisting, essentially, of a fiapextension of the wall so reinforced, adapted to be folded over and lie against the inner surface of the reinforcing medium and provided with means for fastening the flap between its ends to said.wall. i

My improvement may be employed in a box-cover as well as in the box pro er, and it is therefore my intention to be un erstood as including within my invention the. application thereof to each or either of said parts of a box.

In the accompanying dr wings-Figure '1 is a perspective view of a paper-board box illustrating a construction thereof embodying one form of my invention; Fig. 2, a similar view of the same showing the box in its collapsed condition. Fig. 3 is a plan view of the blank from which the box of the 0011- struction illustrated in the preceding figures, is formed' Fig. 4 is a broken perspective view, diagrammatic in its nature, showing a corner-portion of the box in the condition of its representation in' Fig. 2, but with the retaming-flap unfolded; Fig. 5, ,a similar view of the same, showing the retaining-flap in its operative condition; Fig. 6, a similar view showing the parts in their non-collapsed condition, with the retaining flap raised sufficiently to admit under it the folded corner-- portion, and Fig. 7, a view like that present;

Fig. 12 is a view, like that resented by Fig. 8, of the blank for still anot er form of embodiment of my invention; Fig. 13, a broken perspective View of a corner-portion of the box formed from the blank of Fig. 12, but with the'retainingflap unfolded and unfastened; Fig. 14, a similar view of the same showing the flap in its operative condition wherein it is releasably fastened to the folded corner-portion, and Fig. 15, a similar view showing the parts forming a box-corner in. their collapsed condition.

'Each of the three constructions of box setions, or parts thereof, and to be fastened in a manner to'hold them by leaving the ends of the flaps free. p I v Referring particularly to Figs. 1 to 7, in-

' elusive: A 1s the box formed from the blank B, The blank shown consists of a rectangular oblong sheet of pasteboard adapted to be folded along the parallel dotted lines 1 and 2 to form the box-sides band 0 hingedly connected with a base a, and along the dotted lines 3 and 4 to form the box-ends c and d, the dotted lines being, by preference, creases to facilitate folding the parts. Each line 1 and 2 intersects the lines 3 and 4 to form the four rectangular corner-sections 5 of the blank, entirely unsevered therefrom and each of which is ada ted to be folded in wardly on a diagonal ine 6, (also preferably a crease) to form the triangular sections 7 and 8. On each end of the blank is an extension f reaching preferably from the plane of the folding-line 1 to that of the raiding line 2,

upon the other, into thecondition repre-- sented in Fig. 6, against the inner surfaces,

each extension being adapted to be folded at adotted line 9 and form the retaining-flap,

hereinafter described.

To form the box A from the blank B the sections outside the lines 1 and 2 and those outside the lines 3 and 4 are turned to produce, respectively, the side-walls b and c and the end-walls d and e, extending at rightangles to the base a; and in thus forming the walls the corner-sections 5 are turned inwardly along the diagonal lines 6 tofold one ofthe respective box-ends, with the result of affording to the latter at eachcorner-portion of the box a triple-thickness of material and a l consequent reinforcement of the structure.

Each flap f is folded over on a line '9 to lie against the inner surface of the respective reinforced box-end, and is fastened thereto in that position, between the ends of the flap,

-at oneor more points 26, as through the medium of eyelets, buttons,cords or other suitable form of permanent or separable fas-' tener. Thus fastening the flaps leaves each free toward its ends, so that byraising it as indicated in Fig: 6, the respective folded corner-portion 8, 9, may be .inserted or tucked underneath it, whereupon, by releasing the flaps they will assume the position represented of the one shown in Fig. 7, of covering the twoply folds of the corner-portions and thus retain with adequate firmness, the walls of the box, reinforced by the folded corner-portions, in upright condition.

To collapse the box, as for shipment in knock-down condition, into the condition in which it is re resented in Fig. 2, it is only necessary to pul the ends d and e outward, thus turning them on their folding-lines 3, 4 to extend in the plane of the base a, whereby the corner-portlons are withdrawn from underneath the free portions of the flaps f, which yield under the strain and return to their normal condition when the strain is released by the corner-portions clearing them; and with the ends drawn outward to their full extent the corner-portions assume withthe box-sides the flat position against the base represented in Figs. 2 and 5.

To restore the box from itscollapsed c0n dition to that represented in Fig. 1, the ends d, e are turned toward each other, the 0 erby the lines 1 and 2 intersectingthe lines 3, 4, but the diagonal folding-line of crease 6 extends from the respective intersection only to the center of the corner-section 5 while a folding-line or crease 10 extends from said center to the outer edge of said cornersection, and the latter is severed along a struction, with each flap f'fasten'ed, as at w, v

a side-forming part of the blank is turned on its folding-line to extend at a right-angle to the base a, carryingv with it the two cornersections 5 on that side. Each of-the two corner-portions of the box is then formed by folding on a line 10 and thus bringing the parts to the relative positions represented in Fi 9, whereupon the end-section of the blani is turned on its folding-line, as 3, to a right-anglewith the base, and with the adjacent freeend-portion of the flap f raised, as represented in Fig. 10, the part 12, of the.corner-section and the part thereof below the folding-line 10 in Fig. 8 and the part between the folding-line 10-and 9 in the last-named figure are folded one upon the other and tucked under the flap f, thereby bringing the extension g against the inner surface of the side, all as represented inFig. 10. Each corner for the opposite side of the box is similarly formed; and the construction provides a quadruple thickness the corner and a double thickness of the side near the same, with the consequent reinforcing advantage. As will be seen,

this last described construction, which involves the feature of the retaining-flap fastened between its ends, which are free,

may be collapsed into the knock down condition represented in Fig. 11 by turning of material of each box-end near outward the ends, and restored by turning them toward each other, the same as described of the construction represented in Figs. 1 to 7, inclusive.

Referring, particularly, to Figs. 12 to '14, inclusive: The blank B differs from the blank of Fig. 8 in omitting the folding-lines 9 and 10 from each corner-section 5 and extending the diagonal folding-lines 6, as at 6 to the outer edge of the corner-section. A tongue 7 is cut out of the corner-sectionbelow the line 6 to engage with an opening it in the adjacent end of the flap f in converting the blank into a box in collapsed or erect condition.

To form the box A from a blank B each blank-section in turn, frniing a wall I) or c,

is turned to a right-angle with the base a seams and a blank-section forming an end-wall, as d, is similarly and simultaneously turned on its folding-line 9. This brings the triangular piece 12 against the inner face of the endwall, the section 14 containing the tongue h folds inwardly on the line 6, 6 against said piece 12 and the inner face of the endwall, and the piece L5, which is formed by the folding-line 6 and the severing lines 11 and 13 is also thereby brought flatwise against the inner face of the end-wall, and extends perpendicularly from the folding-- line 9 to the base of the box, all as represented in Fig. 13. The tongue h is'thus brought coincident with the adjacent flapopening it, and the respective flap f is then folded on the line 9 to overlap the folded corner 5 and the .tongue h is tucked through the opening 7L either from underneath the flap, as represented in Fig. 14, or the tongue may extend over the inner face of the folded flap to be tucked into its receiving-opening in the latter in an outward direction. The flap is fastened, as'in the other described instances, at x, but the fastening medium penetrates the cornerpiece 15, near its upper end.

To collapse the box of Fig. 14, the tongues 71 are disengaged from their receiving'open;

ings h and the end-walls-of the structure are drawn asunder with the effect of reducing the structure to the condition, represented in Fig. 15, of extending the end-walls in the plane of the base a and folding the side-walls toward each other flat upon the base, while each corner-piece 15, being held by the fastening at ac, and also the corner-piece 12 moves outward with the respective end-wall, remaining flatwise against its inner surface, but the part 14 is turned on the folding-line 6, 6 with the side-wall thus turning'it withdrawing it from underneath the confining end of the flap j: p I

To restore to its erect coindition the box of the last described construction from "its collapsed condition represented in Fig. 15, the end and side-walls are turned'on their -foldiug-lines to extend at right-angles to the base a and the corner-pieces are tucked under the respective free flap-endsand releasably fastened by the tongues h in the manner described. This construction affords to each end-wall, where the corner-piece 15 covers it, a

double thickness, and where the corner-pieces 14-and 12 cover it a triple thickness.

It will be observed that in none of the three illustrated constructions is there any'severance of the blank along eitherfolding-line 1. or 2 between the flap folding lines 9, 9, so that the corner-portions (5, 5, 5 remain unsevered from the blank throughout the said lines 1 and 2, to insure in each instance the triangular inward fold of each box-corner and an unsevered bridging of the reinforcing material across the junction between each end and side-wall. This feature, in connection'with thefree-ended retaining flap, forms an important part of my invention in either of the illustrated embodiments thereof, though it is not indispensable'to my invention,.since the retaining flap, rendered free at its ends by the fastening medium, as m, bet'ween'them, and which is the feature of primary importance inmy invention, may be employed to advantage where the reinforcing medium is;

folded, otherwise than described, against the inner surfaces of the end-walls and whether the corner-portions be severed from the blank along the lines 1 and 2, or not.

What I claim as newand desire to secure by Letters Patent,.is

1. A collapsed box, comprising a base, a pair of side Walls and a pair of end Walls hingedly connected to the base along folding lines, one set of walls lying flat on the base with infolded portions at the ends thereof, flaps hingedly secured to the outer sides of the other settof walls, and means securing each flap between its ends to the wall upon which it is folded with the ends of the flaps overlying the infolded portions.

j 2. A collapsed box, comprising a base, a pair of side walls and apair of end walls hingedly'oonnected to the base along folding lines, one set of walls lying flat on the base with infolded portions at the ends thereof, said infolded portions being also connected to the ends of the other set ofwalls, flaps hingedly secured to the outer sides of the other'set of walls and means securing each'flap between its ends to the wall upon which it is folded with the ends of the fiapsoverlying the infolded portions.

3. A'collapsed box, comprising a base, a

air of side walls and a pair of end walls fiingedly connected to the base along folding lines, one set of walls lying flat on the base with infolded portions at the ends thereof, said infold'ed portions being also connected to the ends of the other set of walls, said infolded ortions being provided with a diagonal 6'5 sis fol line u on which it folds in the erection of the box, 1 aps hingedly secured to the outer sides of the other set of walls and means securing each flap between its ends to the wall upon which it is folded with the ends of the flaps overlying the infolded portions.
